Background And Aim Of Study:
Aortic complications during cannulation must be managed urgently and often require hypothermic circulatory arrest. We report a unique management strategy to repair an aortic tear without dissection by modifying a Dacron ascending aortic graft with side-arm.
Case Presentation:
A 32-year-old female patient undergoing reoperative cardiac surgery suffered an unexpected aortic tear during cannulation for cardiopulmonary bypass. The tear was repaired by utilizing a physician-modified ascending aortic graft with side-arm, in which the surrounding skirt of the side-arm was cut from the circumferential graft to patch the defect. The patient was rewarmed with the side-arm serving as arterial inflow for the bypass circuit, and the remainder of the operation proceeded without complication.
Conclusion:
This type of aortic repair for aortic tears without dissection can offer the patient the benefit of avoiding multiple aortotomies in a weakened aorta, reducing circulatory arrest time, and re-establishing a central cannulation strategy for cardiopulmonary bypass.
